First, a note: I considered actually buying, using, and scanning all of these colors, but I didn’t because a good chunk of them are expensive, toxic, and/or no longer exist. What you’re seeing is a digital approximation of paint-blobs-on-paper.

Second, another note: I got a C- in chemistry, and that was only because the teacher was really, really nice. I’ll do my best to faithfully repeat what I’ve read here, but you could replace all instances of “chemistry” with “magic” and I’d hardly know the difference.
